• Participant gender: All

Summary

This study intends to explore the pathogenesis of obsessive-compulsive disorder(OCD) by using biological technologies such as genetics and imaging, and to evaluate the efficacy of group cognitive behavioural therapy in OCD among the Chinese people. We also prepare to explore the synergistic effect of the pharmacological treatment combined with group cognitive behavioural therapy in OCD, and to find the biological and psychological index which can predict curative effect.

This research includes case control study and randomized controlled single-blind study. At baseline, we compare the dimensions of clinical symptoms, genetics and imaging between OCD patients and healthy controls. The OCD patients are randomly assigned into pharmacological treatment, psychological treatment or pharmacological combined with psychological treatment for a 12-week treatment. After a 12-week treatment, the OCD patients will be divided into valid and invalid groups according to the results of our randomized controlled study by researchers: to our valid group, patients will continue the current treatment, and to the invalid psychological or pharmacological treatment group, patients will have a 12-week combined treatment. From the baseline, we will have a 9-month follow up for both OCD patients and healthy controls.
